Correct statement about sound wave

AI Thread Summary
The discussion centers on the speed of sound waves, specifically the velocities at the centers of compression and rarefaction. The original poster believes that the speed at these points should be maximum, while their teacher asserts it is only at one point. A respondent clarifies that each particle in a sound wave undergoes simple harmonic motion (SHM), indicating that velocity is greatest when displacement is zero. This suggests that the teacher's assertion may be incorrect. The conversation emphasizes the importance of understanding particle motion in sound waves.

My answer is (1) and (2) but the teacher said it is only (1). I thought the speed of point at center of compression and center of rarefaction would be the maximum.

Or the correct one is the speed at center of compression and center of rarefaction would be zero?

Thanks

Your teacher is wrong. Each particle is undergoing SHM and so velocity is the greatest whenever displacement is zero.
 
Thank you very much Orodruin
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
